Abstract

Phosphor conversion of blue radiation from InGaN LEDs has recently gone to a new quality: white light, which is illumination grade in the sense of high color rendering and color temperatures below 4000°K. At the same time power packages taking inputs of 1 Watt or even 5 W and surpassing in efficiency small size halogen lamps have been introduced. After a short review of alternative solutions state of the art devices are described and open questions outlined.
